The most popular scenario is that one of the pilots was locked out of the cockpit. Then, the remaining pilot, for whatever reason, depressurized the cabin. Passengers only have 12 minutes of oxygen from the deployed masks. When that runs out, all persons would fall asleep due hypoxia then after a few more minutes they will die.
Pilots have 1 hour of oxygen from bottles located in the cockpit.
They also say that the person who did this may or may not have committed suicide himself before the aircraft flamed out and entered the ocean.
The aircraft made a number of turns and altitude changes before it adopted its Southerly heading. These turns are verified as fact from Primary Radar installations in Thailand, Malaysia, Vietnam and Indonesia.
I heard that stewards also have bottles that could last for an hour. In fact that's how the stewards of Helios survived...
And how did he lock himself in? Isn't the lock deactivated by punching a code ?
Oh well, never mind...
Cabin Crew also have 12 minutes of oxygen from the same oxygen source as the rest of the cabin.
This oxygen has only one person - to allow passengers and Cabin Crew to survive at very low cabin pressures for a limited time whilst the aircraft descends rapidly to below 13000FT in an Emergency Descent.
The system in the cockpit has another secondary role. It allows pilots to breathe enriched oxygen even at 13000FT.
Most Humans will be able to survive without Oxygen at 18000FT - however, performance is equivalent to a blood alcohol level of 0.2++. In other words, you might as well have drunk a bottle of Scotch. Passengers will have a false sense of delirium until eventually after an extended exposure, the passenger may fall asleep from which they may never wake up from. Other physiological factors are also at play - such as age, smoker/non-smoker, where you live (people who live at high altitudes fare better than those who live at Sea Level), and general health and fitness so it varies from one to another.
At 13000FT, blood alcohol 0.05 to 0.08 with no risk to life.
But there are oxygen bottles within the Medical Storage Bays. The flight Attendant would have to remove their mask in order to get to it. They, potentially will only have 20 to 45 seconds before the collapse into a heap. This goes against all their training. They would also need to be aware that is something is wrong and I doubt they would have been.
And no, no one can open the Cockpit Door from outside. The door can only be unlocked from inside by a switch which disengages the locking rods.
